Thanks for coming to HCM. What you noted as brown discharge can be mild implantation
bleeding. Please follow up your menstrual cycle as you might get pregnant. It's too early so you might not notice pregnancy
symptoms if you are pregnant. If you are not planning to get pregnant, please contact your local gynecologist confirm if you are pregnant or not. Also, discuss with her the contraceptive
methods you can use for future.
Wish you good health.
